Contacting customer support

When troubleshooting Bosch boiler errors, it’s crucial to pay attention to the error codes displayed by the unit. These error codes provide valuable insights into what might be causing the issue and can guide you in the right direction when troubleshooting.

One common Bosch boiler error code is ‘EA.’ This error typically indicates a problem with the boiler’s flame sensor. To troubleshoot this issue, you can start by checking the flame sensor for any dirt or debris that might be obstructing its functionality. Cleaning the flame sensor can sometimes resolve the ‘EA’ error code.

Another frequently encountered error code is ‘H7.’ This code usually points to a problem with the boiler’s water pressure. To troubleshoot the ‘H7’ error, you can check the boiler’s water pressure gauge to ensure that it is within the recommended range. If the pressure is too low, you may need to refill the system with water following the manufacturer’s guidelines.

If you come across the error code ‘A1,’ it typically indicates an issue with the boiler’s water flow. This could be due to a blockage in the water pipes or a malfunctioning water pump. Inspecting the water flow system for any blockages and ensuring that the pump is functioning correctly can help resolve the ‘A1’ error.

For ‘EA’ error code: Check and clean the flame sensor.
For ‘H7’ error code: Verify and adjust the boiler’s water pressure.
For ‘A1’ error code: Inspect water flow system for blockages and check the water pump.

Remember, when dealing with Bosch boiler error codes, it’s essential to refer to the manufacturer’s manual for specific troubleshooting steps and safety guidelines.
